Version 2.93 missing graphics

UPDATE

Accessing the editor from this page under Quick Installation all 5 types return an editor with all panel graphics missing. http://www.codecogs.com/components/equationeditor/equation_install.php#Quick

Accessing the editor from http://www.codecogs.com/components/equationeditor/equationeditor.php returns a working editor.

Can this be fixed urgently?
